Carl Sagan on Time Travel

Listen to the late astronomer and Pulitzer Prize-winning author's insightful and delightfully droll views on everything from wormholes ("very Alice in Wonderland") to the nature of time ("one of those concepts that is profoundly resistant to a simple definition").

Carl Sagan, the astronomer, Pulitzer Prize-winning author, and legendary popularizer of science, gave this interview during the making of "Time Travel." True to form, he discusses arcane aspects of the field - from how you define time to what it might look like inside a wormhole - with flair and a refreshing dash of humor. Sagan was David Duncan Professor of Astronomy and Space Sciences and director of the Laboratory for Planetary Studies at Cornell University when he died in 1996.

NOVA asks:

1) What to you is time?
2) Do you think that backwards time travel will ever be possible?
3) Would you like for backwards time travel to be possible?
4) Can you describe the Grandfather Paradox?
5) Do you think that there are parallel universes?
6) What do you make of Hawking's Chronological Protection Conjecture?
7) What are some of the ways that we can not be awash in time travelers?
8) How is the speed of light connected to time travel?
9) Can you describe a wormhole?
10) What would it be like to travel through a wormhole?
11) How does it feel influencing time travel research?
12) How does it feel bringing time travel a step closer?
